Abstract

A solitary acantholytic acanthoma is a benign tumor which presents as a solitary asymptomatic, keratotic papule or nodule. The acantholysis, implied in the term, is the histologic hallmark. It may mimic pemphigus vulgaris, pemphigus vegetans, or Hailey-Hailey disease, but displays no evidence of these disorders. We report a case of isolated acantholytic acanthoma in a 78-year-old man, where the histologic feature is focal acantholytic dyskeratosis.
